IMPROVED DOOR FOR RAILWAY GARS.

TO ALL WHOM 1T MAY UONCERN: A

y De -itlinowu thutl, D. MARTIX, of Prairie du Chien, in the county of Crawford, and State of Wisconsin, have invented new and useful improvements in the construction and fitting of Doors for Grain Cars; and I do hereby declare the following' to bea full, clear, and exact description thereof, sov that'any one skilled in joinery will be enabled to construct the same reference being had to theannexed drawing, mak-ing part of this specification, in which v Figur-eil is a vertical longitudinal section of a grain car, showing an interior elevation of my invention.

Figure 2 is a transverse section on the line :v :v ot' iig. 1.

Figure 3 is a longitudinal section of acar, showing in elevation a door of greater .length than 'that shown in g. 1.

Figure -l is a transverse section in the line :z: x of igs. 1 and 2, showing the manner of disposing of vthe doors when they are removed from the apertures which thev close.

Figure 5 is a top edge view; and

Figure (i is an outside elevation of -adooiz l Y Figures 7 and S show modifications of the manner of fitting the ends of the doors to their seats.

In all the figures like parts are indicated by the s ame letters of reference.

A A A A"reprcsent the bed and framework of a car for carrying grain, in general construction similar to other ears for the same purpose. The uprights A A are wider than the others,and have secured upon them cleats B B, set at angle with them, so that the space between the upper ends of said cleats sha-ll be wider than that between their lower ends, which rest ou the oor. The door C C C C is of the form of a trapczium, its ends being sloped to suit the inclination of the cleats B B, so that, when the door rests with itslower edge on the floor, and is between the cleats, its ends lshall be in contact with them from top to bottom. To preventthe door from falling inward, cheeks D D are secured on the inside faces of the cleats B B, which project over""the ends of the door, as seen in gs. 1 and 2, and in plan, iig. The uprights A A' prevent the doors from falling outwards. The doors are kept down in theirplaces, when closed, by the pins E E, which pass over the' salient upper corners of the doors, and downward through holes in the cleats B, in a direction which will be at right angles with a line bisecting the angle formed by the top and end of the door. When the door is made of wood, a metallic shoe, F F, iig. G, having a notch on the corner, is placed on each of the upper corners of the door, against which the piu E will bear, while a bolt, G, is passed through the cleat B,- so that the pin E shall be between the shoe F and the bolt G, and be'in contact with bothewhen in place, as shown, in order to preventv the corners of the door and the hole in the cleat B from becoming worn. The. pins E E have eyes at their upper ends, by which they may be secured from loss by being attached to the car with a chain or thong. On the outside of the doors are cleats or braces H H, bolted firmly to the doors, bracing them, and affording the means of easily start-ing them from their bearings, the recesses I I, at the bottoms of the cleats H,being for the purpose of receiving a. bar for prying the doors up it' they 'should have become jammed in their seats. As soon as started, the doors are easily removed, as they are no lonrger in contact with the cleats B. Ledges K K, figs. 1, 2, and 4, are fastened along the inside of the car, and form a pocket for the reception of the door when it is removed from its seat, the door being slid in endways. (See i'lg. 4.) The pocket may be horizontal or inclined. Wherea door is used that would be too long to Stow in a pocket, as above described, the door may have hooks L L, gs. 3 and 4, secured upon itsiupper edge, by which it'may be hung to the eyes M M, fastened to the inside of the car, near the top, so that the lower edge of the door may be swung up towards the roof of the car, and be held there by'bntton N, on the under side of the carlins, fig. 4, or by a spring-catch, or any equivalent device.

The doors and their iittings may be of wood or metal, or a combination of material.

Having thus fully described my invention, what I ela-im as new therein, und desire to secure by Letters Patent, is

As an improvenlcnt'in railroad cars for carrying grain in bulk, I claim the combination of the trapeze shaped door C, inclined cleats B, cheeks D, cleats H, vrecesses I, pins E, notched shoes. F, and bolts G, all cons strueted and arranged to operate as and for the purposes specified.

To the above specilieation of improvement in doors for gra-in cars, I have signed my hand this 7th day of May, 1866. v

Bi MARTIN.
